Speech and Language Processing (3rd ed. draft)
Dan Jurafsky and James H. Martin

• This release finally has a chapter 1! Much LLM material from the former chapter 7 was decanted here, plus lots of new material to make this a fun intro chapter for students as well as other newcomers to the field.

• The former chapter 8 (Transformers) was merged with the remainder of former chapter 7 (=pretraining and decoding/sampling) to create a new single chapter that covers transformers, pretraining, and decoding.

• There is a large stub (about half) of an interpretability chapter 10, more to come on the next edition.

• We used Claude Opus 5 to suggest more exercises for various chapters, and also to do a pass over the first 8 chapters to point out any bugs it could find. It found a lot. The result is some more exercises in this release, and also hopefully fewer typos and subtle notation inconsistencies to plague you the readers!

Here is a single pdf of Aug 19, 2026 book!
